WATER-SHOE.

Speciicationvof Iietters Patent.

Patented Mar. fil/il', milite Application led July 25, 1910. Serial. No. 573,359.

To all whom it may concern.'

Bo it known that. I, KARL HELLMANN, a citizen of thc lnited States, and a resident ot' the city ot New York, borough of Manhattan, in the county and State of New York, have invented a new and'linproved \\":ite1-Sl1 ie, of which the following is a full, clear, and exact description.

The object. of the invention is to provide a new and improved water shoe tor enabling a. person to more forward on a river, lake or other body oi? water, and arranged for convenient attachn'ient to the toot, and having sutiieient buoyancy to properly support the riser on the water and to enable the user' to rapidly xglide over the surface of the water without. danger o't' sliding backward.

For the purpose mentioned the shoe is provided with air-tight compartments, a oot attachment, anda back resistance wingj capable ot swinging into horizontal Vposition on the Jforward stroke of the shoe, and dropping down into resisting position at the end of the forward strolre., thus preventing backwa rd gliding and aty the same. time increasing the stability of the shoe/on the party using' it. i

practical embodiment of the invention is represented in the aeeomplinying drawings forming a part ot' this specification, in which similar characters ot' reference indicate corresponding parts in all the views.

Figure l is a side elevation of the water shoe; Fig. 2 is a plan view of the same, parts being broken out; and Fig. 3 is a rear end view otl a pair of'shoes.

The body A of the shoe is made hollow, and is provided at the forward end with a bow B, and is divided into water-tight oompartments C so as to increase the buoyancy of the shoe for properly supporting a person, it being understood that a shoe is used on each foot. A pit D is arranged in the top of the' body A-for the reception of af-toot' resting on a foot plate E arranged in .the bottom of the pit D, and straps F or other suitable fastening; devices are arranged in the pit l) to strap the foot of the user in position on the foot plate E (see Figx). yllhe body A is preferably made'reetangular in cross seetion and comparatively narrow but long mso that, the two shoes used by a person properly sustain the user and enable him to glide over the water.

'in order to prevent backward sliding. use made ot a resistance wing G, hinged at H to the upper rear edge of a body A, so that the wingnr (if hangs normally downward at the rear end of the body A, and projects a dist/ance below the said body, as indicated in Figs. Il and rl`he wing G is provided at the sides with tlanges G, G2, of which the outer flange G is bent rearwardly and ontwardly, while the'inner flange G2 is bent rearwardly and approximately at a right angle to thc face of the wing G. The ianges G. (im are designed to givel more stability to the shoe, and by bending the inner flange G2 in the manner described the inner flanges di readily pass each other on alternately ,moving the shoes forward when gliding over the water. The wing Gr is provided with a weight. I so as to cause the'wing` to normally hang downward, as plainly indicated inFig. l, it being understood that when the shoe is moved forward the water causes an upward swinging movement of the wing G, so as to lessen the resistance of the latter to the for ward movement oit' the shoe, but as soon as the shoe reaches the. end ot' itsforward stroke,` the wing G drops downward into vertical position so that the wing` offers resistance to the rear moven'xent of the shoe` thereby preventing the person from .glidingr rearward. The upward swinging movement 'of the wing" G is limited by a stop d at tached to the top oi' the body A and pro 'ectinon bevond the rear end thereof, as l a plainly indicated in the drawings.

Having th'ns described my invention, l claim as new and desire to secure by' Letters Ritent:

1. A water shoe, comprising a hollow body provided with attaching means for attaching' the shoe to the foot of the user, and a flanged resistance Wingpivoted on the back of the said hollow body and adapt ed to swing upward on the forward motion of the shoe and to drop down into resisting position at the end of the forwardstroke,

the fianges of the wing standing at dierent angles to the wing.

2. A Water shoe, ,comprising ahollow body provided. with attaching means for attaching the shoe to the foot of the aser, and a resistance wing pivoted on the beck of the said hollow body and adapted to swing upward on the forward motion of theshoe and to drop down into resisting; position at the end of the forward stroke. the wing ha vingr side Hongos (attendingr rearwardly.

3. A water shoe, comprisingr a hoilow body lproa/ided vwith attaching means for attaching the :shoe to vthe foot of the user, and a resistance Wing pivoted on the back of the said) hollow body and adapted to swing upward on the forward motion of the` shoe and to drop down into resisting posi tion at the end of the forward stroke, the' Wing having side flanges extending rear` swing upward on the forward motion of the shoe and to drop downvintoreslsting posi tion al; Jhev end of he yforward stroke, a Weight ioifthe Wing, and a stop on the said hollow body and progecting beyond the rear end thereof for engagement by the Wing at, the time the .latter reaches an approximately horizontal position.

15. ,A Water shoe, comprising a hollow body having a pointed bow and divided into watei-tight coinparti1ie11ts,an attachingdevice for attaching the said body to the foot of the user, and a weighted resistance wing pivoted to the upper edge ofth'e hack of the body to swingnp and down, the said- Wing having a iange at the inner side extending rearwardly approximately at. a right angie tothe Wing.y

i In testimony whereof I have'signed my name to this specification in the presence lof two subscribing witnesses. ,A
